Classification of plant mineral nutrients according to biochemical function

Mineral nutrient	Functions
A.)  Silicon(Si)	1.)    Constituent of alcohol dehydrogenase, glutamic dehydrogenase, carbonic anhydrase, etc
B.)  Manganese(Mn)	2.)    Component of sugar phosphates, nucleic acids, nucleotides, coenzymes, phospholipids, phytic acid, etc. Has a key role in reactions that involve ATP
C.)  Zinc(Zn)	3.)    Contributes to cell wall mechanical properties, including rigidity and elasticity.
D.)  Phosphorous(P)	4.)    Component of ascorbic acid oxidase, tyrosinase, monoamine oxidase, uricase, cytochrome oxidase, phenolase, laccase, and plastocyanin.
E.)   Copper(Cu)	5.)    Required for activity of some dehydrogenases, decarboxylases, kinases, oxidases, and peroxidases. Involved with other cation-activated enzymes and photosynthetic O2 evolution

Mendel crossed Yellow, round and tall pea plants ( YYRRTT) with green, wrinkle and dwarf ones ( yyrrtt). The F1 plants were all yellow, round tall. These F1 plants were cross with YyrrTT. Which of the following proportional of phenotype in progeny?

#Unit 8. Inheritance Biology

Blue follower is dominant over white flower and long pollen is dominant over short pollen. A plant with Blue flower and short pollen was cross with white flower and long pollen. Their progeny, ½ had a blue flower with long pollen and another ½ had a white flower with long pollen was allowed to intercross. Which of the following observation is correct among these progeny when independently assort?

#Unit 8. Inheritance Biology

Genes A, B and C. control three phenotypes which assort independently; A plant with the genotype aaBbCc were cross with AabbCc. What is the probability for progeny which show the dominant phenotype for AT LEAST ONE of the phenotypes controlled by genes A, B and C?

#Unit 8. Inheritance Biology

Male Plant blue flower with long pollen was crossed with female plant white flower with long pollen. Analysis of progeny of this cross showed that 50% of the progeny was red with long pollen while the remaining 50% of the progeny was white with long pollen. Which one of the following statements is a possible explanation of the above results?

Cystic fibrosis is caused by a recessive lethal gene and can be detected by an excess concentration of chloride in sweat. If a sweat test reveals a man to be heterozygous and his wife to be homozygous normal, what are the chances that their children will have the disease?
